Unfortunately for Clemson DE Da'Quan Bowers, he did not step up and shine Friday at his pro day workout. According to sources at the workout, Bowers did not show the elite explosiveness and agility in his workout that he showed on film and this is likely to cause teams to second-guess his ability to be an elite player.

He ran his 40 in the mid-4.8's, was not as quick or agile in the shuttle drills as hoped and was only solid in the broad jump with a 9-6. However, his vertical jump of 34 1/2 is good for a big end like him.

In the end, this workout will likely cause teams to be more concerned about the status of his knee and could adjust his draft status greatly if their medical staff feels his knee issue is going to be a long-term problem (as we have heard some teams believe).

It is important to note that his workout numbers alone should not change his grade if a team feels his knee injury is only a problem now and that he will return to 100 percent eventually.

There are plenty of examples of dominant college players whose draft value fell based on bad workouts before the draft, only to become elite players in the NFL. Baltimore Pro Bowl OLB Terrell Suggs falls in that category.

We are not medical experts, so we will not speculate on a long-term prognosis of his knee. But based on his on-field dominance last season, I would not allow the disappointing workout numbers to change my draft grade on him. He was the best player I evaluated this season, and if his knee gets healthy, I am confident in his ability to be a dominant player in the NFL.
